Public bug reported:
I have an ASUS M3N78-EM motherboard and the problem is that there is no
sound when the nvidia driver
is in use. The sound works if nv driver is used or, if nvidia driver is
in use and ubuntu has been booted with acpi=no option.
When playing something in totem, the pulseaudio volume meters works, and
is possible to see it showing sound but nothing sounds in the speakers.
When going to a console (control+alt+1 for example) the sound starts to
sound in the speakers and when returning to the x display a little noise
sounds and the application playing the sound is automatically close,
totem in this case. The little noise sound always just when entering in
the x display, with nvidia driver and acpi on.
The problem is not only with the integrated sound, also with another
dedicated sound card happens, no sound at all. The integrated one
appears in gnome-mixer as alc1200 and the dedicated one is a pci X-Fi
Xtreme Audio (yes its a X-FI one but it works because is the only X-Fi
with a ca0106 chip, is more an audigy than a x-fi).
I have tried also installing 185 version driver from nvidia but the
problem continues.
